Abstract: Shape-driven is a key factor that affects nanostructure materials and its response to magnetic fields and its energy loss. This makes it a useful design parameter for biomedical and nano-actuation applications. In this study, we present the methodical synthesis and thorough examination of shape-engineered Fe_ₓO_ₓ₊₁ (x = 2, 3) nanodisks (NDs) for regulated magnetic hyperthermia applications. By carefully controlling the ND shapes and oxidation states of iron oxide phases, the specific magnetic and hyperthermia properties was controlled. The engineered NDs show better heating efficiency when exposed to alternating magnetic fields. This is because of the combined effects of Néel and Brownian relaxation processes, which are controlled by shape-induced anisotropy. In-depth structural, morphological, and magnetic analyses show that shape, magnetic loss mechanisms, and functional performance are all closely linked. These Fe_ₓO_ₓ₊₁ NDs have many uses, making them promising, earth-abundant, and biocompatible platforms for the next generation of magnetic hyperthermia therapies and remotely driven nano-actuation systems.
